Abstract

Process for preparing a strongly basic anion exchange resin free of chloride by a two-stage method involving converting covalent chlorine in the resins polymer network to ionic chloride by solvolytic displacement followed by conversion of the resin from the normal chloride form through an intermediate ion form to the hydroxide form, and the strongly basic chloride free anion exchange resin.
